Dmytro Kozatsky is a soldier from Ukraine's Azov regiment and the photographer behind a now-famous collection of photos showing the defenders of the besieged Azovstal steel plant. On May 16, the General Staff of the Ukrainian Armed Forces ordered the commanders of the units in Azovstal to "save the lives of the personnel" there. Four days later, on May 20, Kozatsky reported that he had surrendered. Meduza spoke to his sister, Darya Yurchenko, about why Kozatsky originally decided to join Azov, his life during the siege, and his family's main concerns at the moment.
